The 3M™ PELTOR™ Optime™ III Ear muffs have been developed for use in extremely high noise environments, particularly those dominated by low frequency sounds. The product is based on a technology featuring double cup design to help minimise resonance effect, resulting in excellent high frequency attenuation. In addition, a combination of specially designed spacer and cup helps to provide excellent protection against high frequency sounds.
New technology with double tray minimizes the resonance in the casing · Max. High frequency insulation, signals and voice can be easily noticed at the same time · Acoustic connection between the inner area and the area between the trays provides for an optimal absorption of the low frequencies · Wide, with soft foam filled sealing ring guarantees a good custom-fit and weak pressure · High insulation power and best comfort · CE EN 352-1
